HAIR CUBLER.

Appi'ication. filed October 27, 1928. Serial No. 815,375.

a This, invention relates to a haircur'ler and a more particularly to ahair curler adapted to be used in connection with permanent hair- Wavingmeans, p

5 In curling or waving hair, a tress or plurality of strands of hair istied together-by means of a string adjacent the scalp and then woundspirall on a mechanism, thus pre- 4 paring it for t 1e.;necessarysubsequent treat- 1O ments. Various devices have been devised forwinding the hair as just descnbed. These devices usually included atubular member on which the hair was spirally wound or twisted, arotatable tip member adapted to engage and twist the hair and means torotate said tip member. In the curling or twisting of the hair withthese devices, it was, of course, obvious that the hair must be twistedin one direction whereby it could be tightened to any desired degree. Tosecure this result, various means such as coil springs were suitablydisposed in the device permitting rotation of the tip in one directionand preventing rotation in the opposite direction. Ofttimes, theoperatormanipulated the device in the wrong direction, whereby, due tothe resistance offered by the spring, the latter was deformed andrendered ineffective.

I have found that I can overcome this disadvantage by constructing thecap member, through which rotation is imparted to the tip member, insuch a manner that, when rotated in the wrong direction, it will unscrewitself without deforming the spring or pu ting any substantial strainthereon.-

4 and unscrewing itself when rotated in an opposite direction.

vide a hair curler havin permitting the rotation 0% one direction only,and means whereby said spring means is not substantially strained ordeformed when the device is operated in the opposite direction.

Further objects will appear from the following description, appendedclaims and the accompanying drawing in which:

The figure illustrates a section of the device constituting thisinvention.

It is, therefore, an object of this invention, to provide a hair curlerhaving means manu-Y ally operated for rotating the tip in one directiononly,"said means becoming inefiective Referring now to thedrawingwherein a device constituting this invention is illustrated, thereference numeral 1 designates a tubular member on which the tress, lockor strands of hair adapted to becurled is wound. Rotatably mounted inone end of the tubular member 1 is the reduced end 2 of a bifurcated tip3. Screwed'into the reduced end 2 of the tip member 3 is a rod 4 whichextends through the interior of the tubular member 1. The .other end ofthe rod 4 is screwed v into-one end of a sleeve 5 disposed within thetubular member 1, whereby rotation imparted to the sleeve 5 istransmitted to the tip 3. In order to permit rotation of the tip 3 inonly one direction, one end of a coil spring 6 dis-. posed within thetubular member 1 is secured ,to the sleeve 5 in any suitable manner. The

other end of the sleeve 5 extends beyond the extremity of the tubularmember 1 and is threaded so as to receive a manually rotatable cap ornut 7 through which rotation may be imparted to the sleeve 5. The cap 7is formed with a double threaded bore 8 whereby it may be screwed on tothe sleeve 5. Due to this threading the cap, when rotated in onedirection, will rotate the sleeve 5 and therefore the tip 3. If,however, the cap is rotated in the opposite direction, it will unscrewitself.

In the curling of the hair it is desirable that there be no open jointsoccasioned by the axial movement of the parts or otherwise, whereby thehair may be gripped and /or torn and through which the preparations usedin the treatment of the hair may enter into the interior of the device.With this in view a spring 9 is positioned with oneend thereof bearingagainst the shoulder 10 formed in the cap 7 and the other end bearingagainst a' shoulder or bearing member 11 formed or disposed on thetubular Another object" of this invention is to prospring meansEfon thetip membei 'i'n' properly tied, it is positioned in the slot of the tip3 and the cap 7 manually rotated.

Due to the sleeve 5 and rod 4, the rotationof the cap 7 is transmittedto the tip 3 whereby the hair is twisted and spirally wound on thetubular member 1. If, perchance, the cap 7 is rotated in the wrongdirection, due to its construction it will unscrew itself without anysubstantial deformation or placing any strain on the spring 6 whichprevents rotation of the sleeve 5, and therefore the tip 3, in the wrongdirection. At the same time the spring 11 will immediately expand andtake up the movement of parts. In addition to this,- the s n'ing 9,since it constantly exerts a pressure on the shoulder or bearing member11, will always ur e the tubular member 1 forward, thus taking up anyaxial movement between the tubular member 1 and the tip 3, and alwaysmaintaining a tight,'closed joint therebetween.

Since it is obvious that various changes may be made without departingfrom the invention, it is to be understood that the invention is notlimited to the specific details above described except as set forth inthe appended claims. I

I claim:

1. A. hair curler comprising a tubular member, a rotatable tip mountedon one end thereof, a rotatable sleeve mounted in the other end of saidtubular member, means connecting said tip and sleeve whereby rotation ofsaid sleeve is transmitted to said tip, a cap screwed on said sleeve andhaving threads so disposed that, when rotated in one direc-' in onedirection and causing it-to unscrew' itself when rotated in the oppositedirection, and means for taking up the axial movement between said cap,tubular member and tip.

3. A hair curler comprising a tubular member, a rotatable ti mounted onone end thereof, a rotatable sl eve mounted in the other end of saidtubular member, means connecting said tip and sleeve whereby rotation ofsaid sleeve is transmitted to said tip, a cap screwed on said sleeve andhaving threads so disposed that, when rotated in one direction, it willrotate said sleeve, and when rotated in the opposite direction it willunscrew itself, and means for taking up the axial movement between saidcap, tubular member and tip.

In testimony whereof, I have afiixed my signature to this specification.
